A patient undergoing surgery has few concerns about the success of the operation. The main priority is the effectiveness of the operation itself. However, assurance of anesthesia is equally essential for a patient. The precise methods of applying anesthesia vary depending on the physiological conditions of each patient. The use of clinical anesthesia in obese people is particularly complex and poses dangers for patients. As complications continue to arise following the use of anesthesia in obese individuals, mandatory measures such as additional anesthesiologist training should be implemented at all perioperative stages to reduce the risks for this growing patient population. Obesity is now considered a global epidemic, with numbers particularly concentrated in the United States. In 2011-2012, more than a third of American adults were estimated to be obese (National Center for Health Statistics, 2013). Due to the increasing prevalence of the epidemic, anesthesiologists must care for a significant number of clinically obese patients. A wide range of physiological variations are associated with obesity, including cardiac, respiratory, and metabolic functions (Leykin, v). The areas of concern for anesthesiologists when operating on obese individuals can be separated into three perioperative stages: preoperative, intraoperative, and postoperative. Preoperative concerns primarily focus on each patient's specific medical conditions. As anesthesia is closely tailored to the specific needs of the patient, it is essential that all factors are considered before surgery. This is especially true for obese people, who are likely to suffer from comorbidities (having more than one disease).
